I was a bit nervous about letting an AI edit my code, but the 'Agent Mode' is amazing. I just tell it what I want, it figures out a plan and then shows me the exact changes before actually making them.

Honestly, this extension has been a lifesaver for my daily workflow. I used to spend half my time switching back and forth between the script editor and an AI chatbot, copying and pasting code until my brain fried.
